The “consumer-friendly” term Verification is used synonymously with Authentication, a more technical term. Authentication is the ability to prove that a person (End User) (or something abstract as an application or device) is genuinely who that person (or the application/device) claims to be.
Authentication example: A user takes a Selfie Video which proves that he is alive (Liveness) and sitting in front of the device capturing the information. He then proves (verifies) his Identity by providing some form of government-approved Identification Document (ID) (videos and pictures of it). The biometric information of the Selfie Video is matched against the photograph on the ID. A positive match (Facematch) authenticates a person on the system. The result of this process resembles an Authentication. The Document used for an authentication has a certain DocumentType (e.g. Passport or National ID Card) and is attached to the Authentication. Further, DocumentInformation such as the first_names, last_name, document_number or expiration_date is extracted from this Document (e.g. a Video with many frames or pictures).
